Application filed June 29.1927, Serial No.

My invention relates to doffing apparatus for spinning, doubling, twistng and like machines of the type known as fiyer frames and mypresent'invention consists in the employment of, deviceswhich I arrangeto be actuated by the lifter shaft to secure-the removal ofthe fullbobbins from operating position secures the placingof the emptybobbinsupon the spindles, the retraction of the empty bobbin holders to allowthe raising of the lifter plate and the final advance of the emptybobbin holders intotheir normal positions during the spinningoperations. In connection with the above devices in' accordance with myinvention 1 make use of means for operating the drag cords, devices foradjusting the flyers, cam

operated bifurcations for-clearing or remov- .ing any coils of threadsthat may encircle the spindles, a slotted rod for receiving the threadsso that the attendant may cut or sever said threads by drawing a knifealone;

same, an adjustable receptacle forthe full bobbins and couplingandlbrakedevices for permittingthespindles to rotate under conditionswhich arehereinafterexplained.

In order that my said invention may be readily understood I havehereunto append-' ed sheets of drawings illustrative thereof to which byfigures and letters, reference is made in the following description Fig.1 iwa front elevation of'sufiicient of a flyer spinning frame'to showthe application thereto of my improved parts.

A. A indicate the two end frames ofthe machine.

The devices known as the. lifter mechanism? whichI make use of are ofthe type wherein cam mechanism. causes a horizon tal shaft to oscillateso that by chains taking over chain pulleys fixed thereon, the ris 3extending beneath them awhile their di'iv- Ital f ing pulleys or wharles4 are at their upper arranged to take through the lifter plate in wellknown manner.

The lifterplate 5 is arranged to carry out its'vertically reciprocatingmotions to elfect the building of the coils of yarns on the bobbins inknown manner and by well known cam operating devices which actuate thechain (j-that encircles the pulley 7. This pulley 7 is mounted so thatit may be detached from the shaft 8 during the doiling operations, whileits coupling to said shaft iseifected for carrying-out the usualspinning. process, by devices hereinafter described. v

Fixed upon the shaft 8 and adjoining the chain guiding pulley 7, is aspur wheel 9 which mesheswith a pinion 10 and this pinion is fixed uponthe hub of a hand wheel 11 so that when the operative actuates said handwheel, 11 he may actuate the wheel9.

To couple the pulley 7 to the wheel 9 I employ a clutch bolt 12 which Imount to slide upon one or other of the arms of thewheel 9 so that bythehandle devices 12 said bolt 12 may be made to engage with the-pulley 7in order to couple same to the wheel .9 to enable said wheel to transmitmotion from the pulley 7 to the shaft 8 during the spinning of the yarnand the winding of same in coils upon the bobbins in well known manner.-

The hand wheel 11 and its pinion 10 are mounted upon a stud 11 supportedby appropriate bearings fixed to the end frame A.

The lifter plate 5 is connected to and is operated by the usualchain'devices which are made to encircle chain pulleys fixed upontheshaft- 8 in several positions throughout the length of said shaft 8 inorder to meet the requirements of a longer or shorter lifter plate 5according to the number of spindles in the machine, as is wellunderstood. I

. The drag cords 14, are connected at the rearof the spindles 3, teasliding rod 14* and to the front of the'spindles to another notchedsliding rod 14"(see'Figs. 2 and 3) so that during thespinning operationstheir weights 14; may cause said drag cords 14 to press against theedges of-the lower flange's of the bobbins 13 in well known manner. i 3l As is well known, the drag on the bobbins 13 during, the buildingoperations has to be increased andto effect this increase the drag cordsare gradually moved to press more firmly against the flanges of thebobbins as thefcoils of yarn thereon increase in diameter. To. securethis increase of drag action I employ the well known ratchet wheel andworm devices (not shown in. the drawings) whiclrmove the two slidingbars 14:;and 14" fromright to left in order to cause the drag cords 14;to more firmly press upon the flanges of the bobbin 13 to meet theincreased leverage which the threads exercise over the bobbins uponwhich they have been wound as is well understood.

When the coils of yarns are being wound upon'lhe bobbins 13 to fill saidbobbins in known manner, the lifter plate 5 is raised and lowered orreciprocated in its vertical path through its usual space to control theguiding of the yarns upon the bobbins from the lower to the upper endsof same throughout the spinning operations until the bobbins are filled,and during said operations the lifter plate 5'is actuated by its cammechanism in the ordinary and usual manner during which no motion istransmitted to any other part which I employ for the doll ing processhereinafter described.

In order to carry out said dolfing process according to my presentvinvention I make use of the devices above explained to dis engage themechanism which actuates the lifter plate during the spinning proccss,loallow said lifter plate to be separately operated to effect thedofiingr.

.1As means for performing these dolling actions, I fix cams upon theshaft 8 for at footing the further and necessary movements. That is tosay, to secure the levelling; or adjusting oi the flyers 2 I mount a cam16 (shown by Figs. 5, 12 and 18 and hereinafter more fully described)upon the shaft 8 and this cam 16 is arranged, by the lever-116", to movea bar 16 which is carried upon the end of the lever 16 that is supportedby bearings 16 fixed to the framework of the machine. This bar 16"extends longitudinally the length of the machine to be sup ported byother lever arms (similar to 16) also mounted upon fixtures carried bythe framework of the machine. thus the bar '16" may be movedlongitudinally by its cam 16 and will be supported by the lovers '16throughout its longitudinal movement. i a On the bar 16" are pivoted twoor more levers 16. according to the length of the machine, and the rearends of the levers 16 are actuated by a spring 16 which keeps or tendsto keep said lever-.16 in their advanced positions. The levers 16? aresullicient in number to support another bar 16 which ex tends the fulllength of the machine in order that the inclinesaon the front edge ofsaid bar 16- may come in contact with the legs of the fiyers 2 somewhatas is shown by Fig.

5, by which means when the cam 16 is 1'0 tated by the shaft 8 it willactuate thewhole series of flyers 2 to bring their legsinto orapproximately into the same vertical plane.

Also fixed on the shaft 8 is another cam 17 (of a formation hereinafterdescribed) and this cam 17 actuates the lever 17 (which is pivoted uponthe framework of the machine) so that said lever 17, may, by the rodIll) 1'7 actuate a lever 17 which is fixed upon a shaft 17. y

'This shaft 17 is supported by the framework of the machine and has aseries of arms 17 fixed uponflit the number of said arms beingsuflicient to carryor support a longitudinal shaft 17 whiclris swivelledon the outer ends of same.

Upon this swivelling shaft 17 (which is preferably square in crosssection) are mounted bifurcated members 17% (corresponding in numberwith that of the spindles 3) which will when being moved, span thespindles 3 so as to wipe or carry away the coils of threads extendingfrom the legs of the flyers and encircling said spindles 3 afterthe'full bobbins have descended beyond the lower endsyof same as is wellknown. l a i V In an appropriate position upon this square shaft 17isfixed a lever 17 (see Fig. 10) so that a stud 17 extending laterallytherefrom may take beneath a cam piece 17 fixed upon a bracket 17 whichis secured to the frame-work of the machine. Thus as the cam 17isrotated (as ishereinbefore described),yand as it is carried by theshaft 8, the lever 17 will cause the levers 17 and and said shaftl't' tooscillate. This oscillation of theshaft li' by the actions of the-cam 17brings the arms 17 so that the shaft 17 carrying the bifurcated member17 will cause these latter to span the spindles 3 as is shown by-Fig. 9.The motion transmitted to the shaft l in this forward direction is suchas to cause said shaft to carry its lever 17 'in order that the stud 17will pass the lower end of the cam piece 17? at the point 6 (Fig. 10).'Here it will encounter the hinged piece 17 which is free reaching thepoint where thehinged plate 17 will engage with the stud 17 k theactions of the cam 17 upon the stud 17? are reversed during "the reversemovement of the shaft 8 as is hereinafter described. and at this timethe shaft 17 will be tilted so that the bifurcations 17 will-ascend totheir positions shown by Fig. 14Ibypassing through a path which liesclear of the lifter plate 5, the spin- .dles and any bobbinsthat may bemounted thereon. This is effected by the stud 17 following thecontour ofthe cam piece 17* until its normal position (as shown by Fig. 10) isreached. i

Fixed upon the same shaft 8 is another cam 18 (formed as hereinafterdescribed) which operates the lever 18" and this lever 18 is connectedby a rod 18 to a lever 18 fixed upon a longitudinal shaft 18. This shaft18 extends lengthwise the machine and has fixed upon it the arms 18 Atthe upper ends of these arms 18 is fixed a longitudinal rail 18 and uponthis longitudinal rail are fixed a series of bobbin engaging members 18These members 18 are for engaging theupper flanges of the bobbins 13 asshown by Fig. 1% as well as acting as displacers for the full bobbins.

To enable the member 18 to engage with the bobbins 18 slots 0 (see Fig.4:) are formed laterally in said members 18 to span the barrel parts ofthe bobbins 13 and yet to carry the upwardly projecting flanges (Z whichextend from the engaging members 18 to receive and overhang the flangesof the bobbin, also shown'by Fig. 1-4.. v i

The cam 18 is arranged to have a part of its surface to occupy a normalposition shown'by Fig. during the spinning operations and in said normalposition the engaging members 18 may have placed upon them the emptybobbins 13 as is shown by Figs. 14: and 15 while whenthe cam 18 isrotated by the shaft 8 said members 18 may be moved from the said frontposition .15 where all the bobbins will be held clear of the spindles oand lifter plate 5. This. extension 18 from the rail v18 ,to the rear ofthe barrels of the bobbins 13 are employed so that they may support thebobbins in a lateral. directionand keep them in proper position, as isshown in broken lines Fig. 15 to enable them to clear or push away thefull bobbins as is hereinafter described.

The lifter plate 5 is actuated by the known devices hereinbeforeexplained and is provided with known means whereby the longitudinal barsto which the drag cords 14 aresecured are caused to advance as is setforth. During their advancing move: ments they will earrywith them thebracket 19. at the lowerendof which is pivoted a small runner 19 so thatsaid runner may groove in afixed cam plate or bowl or runner .19 movingwithin the broader grooved part 19 of thecam plate 19 'However, when thedoiiing operations are to commence said runner or bowl 19 on descendingwith the lifterplate 5 will come in, contact with the inclined edge dofthe flanges of the lower end of the bobbins and when the attendant,readjusts the lifter plate into its working position as is shown by Fig.1 thebowl 19, will, by coming in con tact with the inclined part cl ofthe cam plate 19", have caused the bars 14: and 144 to move from theirposition where the cords were clear of the bobbins so as to bring samebars and their cords into the desired position against the edges of thebobbins on reaching the position shown by Fig. 1 in which case all ofthe cords are readjusted into position so as to place the least amount pof drag required upon the bobbins 13 at the commencement of the spinningoperation, the increasing of said drag being effected by the deviceshereinbefore described.

lVhile the shaft- 8 is being oscillated to carry out the verticalreeiprocationsof the lifter plate 5 during the process of spin ning, thecam 16 is not moved suiliciently far to bring its cam surface to actupon the lever lti hence during said process of spinnin said lever 16and all the parts it moves or operates, are stationary. In like mannerand during the same actions the operating grooves in the cams 17 and 1Spermit these latter to be moved by the shaft 8 without bringing theircam surfaces into action, thus. at thistime the devices they actuateremain in their normalinoperative positions.

The operations of the several parts are as follows After the bobbins 13have been filled with the coils of yarn as is shown by Figs. 1a and 15,and at the same time the series of empty bobbins 13 have been placed bythe attendant upon their engaging members 18", the attendant willdisengage the coupling bolt 12 by actuating the handle 12 so as to freethe pulley 7 from its connections with the shaft 8. He may then actuatethe hand wheel 11 and by the pinion l0 and wheel 9, cause the shaft torevolve in order to lower the lifter plateb beyond the position wherethe upper ends of the full bobbins 13 would be clear of the lower endsofthe flyers as is shown by Figs. 12 and 13. After this position is,reached by continuing the motions of the hand wheel 11 the lifter plate5 will continue to descend and simultaneously with the descending ofthis lifter plate 5 the cam 16 will now have brought the flyer operatingbar '16 into its position shown by Fig. 5 so that all the flyers areadjusted in the desired position.

Shortly after the adjusting of the flyers in the position described, thecam. 17 will have operated theshaft 17 so that the bifurcations 17 willengage with the spindles 3 by spanning same; thus ou descending theywill remove any coils of yarn that may be encircling said spindles 3,and the continued motion of the bifurcations 17 will carry said yarnsbeyond the lower ends of the spindles. Simultaneously with the actionsof the cam 16 to bring the legs of the flyers into alignment, andcommencing at about the same time, thecaln 18 will actuate the bobbinengaging members 18" and will remove same from their positions shown infull lines Figs. 14; and 15 to the rear position shown in broken linesof Fig. 15 so that said bobbins 13 are moved clearv of the lifter plate5 during its descent. After the lifter plate 5 has descended with itsfull bobbins past where the empty bobbins are shown in broken lines Fig.15 down to its lowest position, the cam 18 will, bycontinuing in motioncause the members 18 to advance from their rear position shown in brokenlines Fig. 15 to the position shown in full lines by said Fig. 15, therethey will have encountered the full bobbins and, will have pushed sameoff the lifter plate 5 as is shown in broken lines Fig. 15 in order thatthey will descend into a trough or receptacle 20 which extends thelength of the machine.

' \Vhen the empty bobbins 13 have reached this last named position withall the full bobbins cleared away from the lifter plate, the attendantwill reverse the direction of 1no- ,tion of the hand wheel 11 and willthereby reverse the niotionsof the shaft 8 in order to carry the severalcams back to the normal positions which they occupy during the spinningoperations, and in doing this the lifter plate will move from itsposition shown in broken lines by Figs. 14 and 15 to raise the emptybobbins 13 onto the lower ends of the spindles 3 and so soon as saidbobbins 13 have been moved for a sufiicient space over the ends of thespindles 3, the cam 18 will again cause the bobbin engaging members 18*to move to the rear of the lifter plate 5 in order to permit said lifterplate to rise into its operating position above said engaging members 18When the lifter plate 5 has thus ascended above the members 18 theselatter will re turn to their normal forward positions where again thebifurcations may (afterwards and after tlie'spinning process has beencommenced) receive their supply of empty bobbins as will be understood.On the lifter plate 5 being further raised, by the movement of the handwheel 11 carrying the wheel 9 into position for the engaging bolt 12toen gage with the pulley 7, all the dofiing operas tions will have beencompleted and every part of the dotting mechanism will have been rcadjusted in its respective position ready for the spinning operations tobe re-started.

The machine is then put into motion until a few coils of yarn are woundupon the newly supplied empty bobbins, when the machine is againarrested, all the loose or extending yarns from the bobbins on thespindles 3 to those in the receptacle 20 (see Fig.

, knife along the groove l3) will extend over a longitudinally groovedbar .21 acrossv the groove 21 in which are made other grooves 21 innumber to the spindles in and therefore to the threads therefrom.

the machine that extend Before starting the machine into further of saidbrake devices and coupling means' are in suchtpositions as to retard orhinder the flyers and their spindles from revolving so that difficultymight arise when the flyer adjusting mechanism was brought into use. To.avoid this I make use of a rod (see Figs. 10,and11).which I fix upon theends of levers 31 so th-atsaid rods 30 mayextend above the operatinghandle devices 32 which actuate the brake and coupling mechanismdescribed. The lever 31 at the end of the machine shown is pivoted at 31and is coupled by a rod 33 to a lever 34 pivoted at 35 so that a bevelwheel or quadrant 36 fixed to said lever 34 may engage with anotherbevel wheel '37 that is fixed to a horizontal lever 38. This lever 33 isconnected to the starting rod 39tl at extends lengthwise thezmachine sothat immediately the attendant operates the starting handle 40 to stopthe machine prior to dotting, the shaft 40 will oscillate and cause thelever 41 also to oscillate. To this lever 41 is connected the rod 39hence the oscillating of the lever 41 will cause said rod 39 to be movedlongitudinally to operate the lever 38 so as to depressthe longitudinalrod 30 thereby relieving all the handle devices which operate theclutches and brake mechanismso that the flyers 2 and their spindles 3may then be rotated freely. 1

. The receptacle 20, which receives the full bobbins when same areforced forward to fall from the lifter plate is of the formation shownby Fig. 13, and isarranged to be supported by. extend from the frameworkof the machine; From the rear lowerfedge of this receptacle 20 aprojection 43 extends which carries a bowl 44.

This .bowltakes into a guiding slot 45 so thatas. the. extending end ofa hand actuated lever (not shown by the drawings) movesthe rod 46 whichis coupled to it. and to abracket 47 on the receptacle 20, in arearwa'rddirection, saidreceptacle 20 will be, moved from theposition shown infull lines Fig. 13 (Where it will receive the fullbobbins) into theposition shown in broken lines of the same figure and in this (see Fig,12) equal yarns are cut and the ma.

a seriesof brackets 42which position may be used as a platform for theattendant. to step upon when reaching articles from the upper parts ofthe machine.

Such being a the nature and object of my saidinvention what I claimis::-'
